• Petrochemicals

• Power

• Steel

Applications

• Agitated liquids in tanks

• High accuracy applications where ±2 mm / 0.08¨ is specified

• Long-range liquid level applications up to 100 m / 328 ft

• Fast moving processes (≤60 m/min / 196.85 ft/min)

1.2 Applications

1. Level measurement of liquidsThe level transmitter can measure the level of a wide range of liquid products on a large variety of installations within the stated pressure and temperature range. It does not require any calibration: it is only necessary to do a short configuration procedure.

2. Volume (mass) measurementA strapping table function is available in the configuration menu for volume or mass measurement. Up to 50 volume (mass) values can be related to level values. For example:

Level ➀= 2 m / Volume ➀= e.g. 0.7 m³ Level ➁= 10 m / Volume ➁= e.g. 5 m³ Level ➂= 20 m / Volume ➂= e.g. 17 m³

This data permits the device to calculate (by linear interpolation) volume or mass between strapping table entries.

PACTware™ software and a DTM (Device Type Manager) is supplied free of charge with the device. This software permits the user to easily configure the device with a computer. It has a conversion table function with a large number of tank shapes.

1.3 Measuring principle The radar principle used is FMCW (Frequency Modulated Continuous Wave).

The FMCW-radar transmits a high frequency signal whose frequency increases linearly during the measurement phase (called the frequency sweep). The signal is emitted, reflected on the measuring surface and received with a time delay, t. Delay time, t=2d/c, where d is the distance to the product surface and c is the speed of light in the gas above the product.

For further signal processing the difference Δf is calculated from the actual transmitted frequency and the received frequency. The difference is directly proportional to the distance. A large frequency difference corresponds to a large distance and vice versa. The frequency difference Δf is transformed via a Fast Fourier Transform (FFT) into a frequency spectrum and then the distance is calculated from the spectrum. The level results from the difference between the tank height and the measured distance.

Measurement modes“Direct” mode

If the dielectric constant of the liquid is high (εr ≥1.4), the level signal is the reflection on the surface of the liquid.

“TBF Auto” mode

If the dielectric constant of the liquid is low (εr 1.4...1.5, for long-distance measurement), you must use "TBF Auto" mode to measure level correctly. "TBF Auto" is an automatic mode that lets the device make a selection between "Direct" mode and "TBF" mode. If the device finds a large radar reflection above the "tank bottom area" (the bottom 20% of the tank height), the device will use "Direct" mode. If the device finds a large radar reflection in the "tank bottom area", the device uses TBF mode. This mode can be used only in tanks with flat bottoms or in stilling wells with a reference plate at the bottom.

“Full TBF” mode

TBF = Tank Bottom Following. If the dielectric constant of the liquid is very low (εr <1.4), you must use "TBF Full" mode to measure level correctly. The device uses the radar reflection on the bottom of the tank (the signal goes through the liquid). This mode can be used only in tanks with flat bottoms or in stilling wells with a reference plate at the bottom.

Number of devices that can be operated in a tank

Figure 3-3: There is no maximum limit to the number of devices that can be operated in the same silo

3.3.3 Mounting restrictions

LPR and TLPR devices

LPR (Level Probing Radar) devices measure level in the open air or in a closed space (a metallic tank etc.). TLPR (Tank Level Probing Radar) devices measure level in a closed space only. You can use LPR devices for TLPR applications. For more data, refer to Order code on page 34, antenna options.

Causes of interference signals

• Objects in the tank or pit.

• Sharp corners that are perpendicular to the path of the radar beam.

• Sudden changes in tank diameter in the path of the radar beam.

Do not install the device above objects in the silo (ladder, supports etc.) or pit. Objects in the silo or pit can cause interference signals. If there are interference signals, the device will not measure correctly.

If it is not possible to install the device on another part of the silo or pit, do an empty spectrum scan. For more data, refer to the handbook.

Equipment and obstacles: how to prevent measurement of interference signals Do not put the device immediately above equipment and obstacles in a tank or pit. This can have an effect on the performance of the device.

If possible, do not install a nozzle on the tank centerline.

31

Figure 3-4: Equipment and obstacles: how to prevent measurement of interference signals

➀ Do not tilt the device more than 2° ➁ We recommend that you do an empty spectrum recording if there are too many obstacles in the radar beam (refer to the

handbook).

➂ If there are too many obstacles in the tank, you can install the device on a standpipe. For more data about how to install the device on standpipes, refer to Standpipes (stilling wells and bypass chambers) on page 35.

➃ Beam radius of the antenna: refer to the table below. The beam radius increases by increments of "x" mm for each metre of distance from the antenna.

Product inlets

Figure 3-5: Product inlets

➀ The device is in the correct position. ➁ The device is too near to the product inlet.

Do not put the device near to the product inlet. If the product that enters the silo touches the antenna, the device will measure incorrectly. If the product fills the silo directly below the antenna, the device will also measure incorrectly.

For more data about the measuring range of each type of antenna, refer to Measuring accuracy on page 15.

3.3.5 LPR devices: recommendations for pits and tanks made of non-conductive materials

These instructions are for LPR equipment only. For more data, refer to Order code on page 48, antenna options.

Device installation on tanks made of a non-conductive material

Figure 3-8: Device installation on tanks made of a non-conductive material

➀ LPR equipment on a basic support (for indoor installations) ➁ LPR equipment on a sealed support ➂ LPR equipment on a tank made of conductive material, but with a non-conductive, sealed "window"

If the device cannot go in the tank and the tank is made of a non-conductive material (plastic etc.), you can attach a support to the top of the tank without a hole in the tank roof. We recommend that you put the antenna as near as possible to the top of the tank.

If the tank is outdoors, we recommend that you seal the support. If rain is on the top of the tank and directly below the device, this can have an effect on the device performance.

If device is used in dusty conditions, we recommend that you seal the support. If dust is on the top of the tank and directly below the device, this can have an effect on the device performance.

Open pits

Figure 3-9: Open pits

If the device must measure the level of product in a pit, you can attach a support to the side of the pit or above the pit.

These instructions are applicable for devices with Metallic Horn antenna options only. Use a

standpipe if:

• There is highly conductive foam in the tank.

• The liquid is very turbulent or agitated.

• There are too many other objects in the tank.

• The device is measuring a liquid (petro-chemicals) in a tank with a floating roof.

• The device is installed in a horizontal cylindrical tank.

Figure 3-10: Installation recommendations for standpipes (stilling wells and bypass chambers)

➀ A stilling well solution ➁ A bypass chamber solution ➂ Air circulation hole ➃ Level of the liquid

• The standpipe must be electrically conductive.

• The inside diameter of the standpipe must not be more than 5 mm / 0.2¨ over the diameter of the antenna (for a high-dielectric constant liquid).

• The standpipe must be straight. There must be no sudden changes in internal diameter greater than 1 mm / 0.04¨.

• The standpipe must be vertical.

• Recommended surface roughness: <±0.1 mm / 0.004¨.

• Make sure that there are no deposits at the bottom of the standpipe.

• Make sure that there is liquid in the standpipe.

You must drill an air circulation hole. Installation in tanks containing one liquid and foam

• Drill an air circulation hole (max. Ø10 mm / 0.4¨) in the stilling well above the maximum level.

36

Installation in tanks containing one liquid and foam


• Remove the burr from the hole.

Installation in tanks containing one liquid or more without foam


• Drill 1 or more liquid circulation holes in the stilling well (if there is more than 1 liquid in the tank).

• These holes help the liquid to move freely between the stilling well and the tank.

• Remove the burr from the hole.

Stilling wells: floating roofs

If the device must be installed on a tank with a floating roof, install it in a stilling well made of

metal.

➀ Sediment ➁ Support fixtures ➂ Stilling well ➃ Floating roof ➄ Product ➅ Tank

37

Stilling wells: horizontal cylindrical tanks

We recommend that you install the device in a stilling well if the device:

• is for a horizontal cylindrical tank,

• is in a metallic tank,

• measures a product with a high dielectric constant and

• is on the centerline of the tank.

Figure 3-12: Horizontal cylindrical tanks

➀ The device is installed without a stilling well. There are multiple reflections. Refer to the CAUTION! that follows. ➁ The device is installed in a stilling well and measures correctly.

If the device is installed in horizontal cylindrical tank that contains a high dielectric constant liquid without a stilling well, do not put it on the tank centerline. This will cause multiple reflections and the device will not measure accurately. Use the device software to keep the effects of multiple reflections to a minimum. For more data, refer to "Function description" in the handbook.

38

Bypass chambers

Installation next to tanks containing one liquid and foam

• The top process connection of the bypass chamber must be above the maximum level of liquid.

• The bottom process connection of the bypass chamber must be below the lowest measured level of liquid.

Installation next to tanks containing more than one liquid

• The top process connection of the bypass chamber must be above the maximum level of liquid.

• The bottom process connection of the bypass chamber must be below the lowest measured level of liquid.

• Additional process connections are necessary for the liquids to circulate freely along the length of the bypass chamber.
